I mean being able to remote into the thing, have it stored in the rack etc. is nice and all - but if you don't absolutely need ECC, it would make a lot of sense to slap a water block on Chagall Threadripper and enjoy even higher single thread performance right?

[@alangarde2928]

Really depends on your use case. Personal workstation/home server, go Threadripper. Enterprise server - it's a different set of factors. How much memory you want in it for one thing, 1TB+ of memory for 8 cores isn't an unreasonable thing - especially in a two socket system with 16 cores. How much storage you want to directly hang in the box and how many PCIe lanes/iops you want to push through it. Then there is the whole server chassis thing. Redundant power supplies, hot swap fans, is the hardware and CPU designed to be run 24/7 under load, etc. How important is uptime to you? It is more than just being able to remote into it and have it in a rack, what's the cost of maintaining it for you and the impact of it being down. When you start looking at 10, 100, 1000 of these, these stop being nice to have features and become must have so you don't have a fleet of engineers keeping them running and the amount of power and cooling you are looking at. There is kind of a vague line I've seen in small shops that can use consumer/prosumer stuff , maybe because each box only effects one user - lots of power, relatively low costs. Other side of the line your business grows and suddenly extra headroom in storage, memory, enterprise reliability (especially say if now its half a dozen people who stop work if it's down) when it stops trying to get the most raw power out of the price and other factors to the business outweigh the initial outlay.

It's optimized for different things, like power usage and bandwidth, over pure clock speed. Even at 8 cores, these could probably move far more data around than a desktop part. Also, the common way to make these is to use defective chips. Laser off the bad cores, and you have more thermal headroom and cache per core.

[@utkarshanand9706]

Having more cores was randomly chosen as a way to improve performance of chips when chip designers were unable to do anything else. It's not necessarily a good way to even expect processes to function, although programmers have somewhat adapted to it. There are several other ways to advance the capabilities of a chip, for example, getting IPC improvements is one and there are people out there who're designing chips around this principle. However, I believe that the frequency improvements that I can get with my hardware will outcompete anything else. For an average consumer, I'd say that my products will change your mind on your perception of high core count.

[@evoblade2000]

More cores were not randomly chosen. It was the only avenue left that offered significant performance gains with any feasible technology. Originally they thought they were going to just keep building faster and faster CPUs (like 8 GHZ+) but physics said no.
